Description
WasserbelütunwsrohrWasserbelütunwsrohr
Die Erfindung betrifft ein,Wasserbelüftungsrohr nach dem Gattungsbegriff des 1. Patent-anspruches.The invention relates to a water ventilation pipe according to the generic term of the 1st patent claim.
Bei diesen Belüftungsrohren soll eine möglichst feinblasige Belüftung erreicht werden, um so bei grosser Luftausnutzung einen hohen Sauerstoffertrag zu gewährleisten. Wenngleich eine grosse Anzahl feiner Schlitze im aussen liegenden Schlauch zu entsprechend vielen Luftblasen führt, besteht die Gefahr, dass sich mehrere Luftblasen zu einer grösseren Blase vereinigen.In the case of these ventilation pipes, ventilation should be as fine-grained as possible can be achieved in order to achieve a high oxygen yield with a high level of air utilization guarantee. Albeit a large number of fine slits on the outside Hose leads to a corresponding number of air bubbles, there is a risk that it will combine several air bubbles into one larger bubble.
Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, die obigen Rohre so auszubilden, dass die Gefahr einer unerwünschten Vereinigung der Luftblasen weitgehend ausgeschaltet wird.The invention is essentially based on the object of the above Pipes should be designed in such a way that there is a risk of undesired association of the air bubbles is largely turned off.
Aufgrund der Erfindung hat der unten liegende, vor der Durchbrechung des Stützrohres befindliche Abschnitt des Schlauches eine Erstreckung, die etwa 1/5 bis 1/2 des Schlauchumfanges entspricht; vorzugsweise hat dieser Abschnitt jedoch eine Erstreckung, die etwa 1/3 des Schlauchumfanges entspricht.Due to the invention, the one below, in front of the breakthrough of the support tube located section of the hose an extent that is approximately 1/5 to 1/2 of the hose circumference corresponds; however, this section preferably has an extension that corresponds to about 1/3 of the hose circumference.
Ein grosser Teil des unten liegenden Abschnittes des aussen liegenden Schlauches ist somit frei von Schlitzen.A large part of the lower section of the outer one The hose is therefore free of slits.
Damit werden aber Luftaustritte weitgehend ausgeschaltet, die nicht unmittelbar in das Wasser eintreten, sondern ihren Weg zunächst entlang des Schlauchumfanges nehmen, wobei sie auf andere Luftblasen treffen und sich dann mit diesen vereinigen. Wird indessen ein schlitzfreier Abschnitt gemäss Erfindung gewählt, so treten praktisch alle Luftblasen an Stellen aus, die einen unmittelbaren Ubertritt in das umgehende Wasser gewährleisten. Unter diesen Voraussetzungen sind aufgrund der durchgeführten Versuche grössere Luftblasen ausgeschlossen; ein feinblasiges Belüftungsbild ist das gewünschte Ziel.However, this largely eliminates air leaks, which are not enter the water directly, but instead make their way first along the circumference of the hose where they meet other air bubbles and then merge with them. If, however, a slot-free section is selected according to the invention, it is practical all air bubbles in places that have an immediate crossover into the immediate Ensure water. Under these conditions are carried out due to the Attempts to avoid larger air bubbles; is a fine-bubble ventilation pattern the desired destination.
Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel der Erfindung dargestellt ist.Further details of the invention are explained with reference to the drawing, in which an embodiment of the invention is shown.
Es zeigen Fig. 1 ein Druckluftwasserbelüftungsrohr in der Seitenansicht und Fig. 2 das Rohr gemäss Fig. 1 im Querschnitt.1 shows a compressed air water ventilation pipe in a side view and FIG. 2 shows the pipe according to FIG. 1 in cross section.
Das Stützrohr 1 besteht aus einem steifen, harten Kunststoff, es hat unten an seiner tiefsten Stelle eine Durchbrechung 2, die aus Langlöchern bestehen kann, welche eine Reihe bilden. Das Sützrohr 1 kann beliebig gehalten sein; die Druckluftzufuhr erfolgt über einen Stutzen 3. Dabei können auch zwei Stützrohre 1 einem Anschluss zugeordnet sein.The support tube 1 consists of a rigid, hard plastic, it has below at its deepest point an opening 2, which consist of elongated holes can, which form a series. The support tube 1 can be held arbitrarily; the Compressed air is supplied via a nozzle 3. Two support tubes can also be used 1 must be assigned to a connection.
Das Stützrohr 1 wird eng von einem Schlauch 4 umschlossen, dessen Enden durch Schellen 5 festgehalten sind.The support tube 1 is tightly enclosed by a hose 4, the Ends are held in place by clamps 5.
Über den oben gelegenen Umfangsbereich S hinweg ist der Schlauch 4 mit feinen Schlitzen 6 versehen, die in mehren Reihen dicht bei dicht angeordnet sind. Diese etwa radial verlaufenden Schlitze 6 sind bei 7 angedeutet; sie können eine Länge von etwa 1.5 mm haben bei einem Schlitzabstand von etwa 2.5 mm. Der Abstand benachbarter Reihen kann dabei 2.2 mm ausmachen.The tube 4 extends over the circumferential area S located above provided with fine slots 6, which are arranged in several rows close together are. These approximately radially extending slots 6 are indicated at 7; you can have a length of about 1.5 mm with a slot spacing of about 2.5 mm. The distance adjacent rows can be 2.2 mm.
Der nicht mit Schlitzen 6 versehene, am weitesten unten gelegene Bereich vor der Durchbrechung 2 soll somit gross sein. Damit wird nicht nur eine Verbesserte Abdichtung der Durchbrechung 2 bei nicht eingestellter Druckluft, sondern weiterhin noch erreicht, dass im unteren Teil des Schlauches 4 keine Luftblasen austreten können, die sich zunächst an der Aussenfläche des Schlauches 4 entlangbewegen und dabei zu einer Vereinigung mit anderen Luftblasen führen können. Vielmehr gelangen nunmehr alle austretenden Luftblasen unmittelbar und selbstständig in das Wasser. Dies ist durch Pfeile 8 angedeutet.The area furthest down, not provided with slots 6 in front of the opening 2 should therefore be large. Not only does it become an improved one Sealing of the opening 2 when the compressed air is not set, but continues still achieved that in the lower part of the hose 4 no air bubbles emerge can, which initially move along the outer surface of the tube 4 and can lead to a union with other air bubbles. Rather, get there now all emerging air bubbles directly and independently in the water. This is indicated by arrows 8.
Nach dem bevorzugten Ausführungsbeispiel gemäss Zeichnung ist der Bereich S so gross, dass er 2/3 des Schlauchumfanges ausmacht; demgemäss ist der erwähnte kritische Bereich etwa so gross, dass er 1/3 des Schlauchumfanges beträgt.According to the preferred embodiment according to the drawing Area S so large that it makes up 2/3 of the hose circumference; accordingly is the mentioned critical area about so large that it is 1/3 of the hose circumference.
Es sei noch erwähnt, dass aus Gründen der einfacheren Darstellung der Schlauch 4 keine Querschnittsschraffur erhalten hat, um so auch die Schlitze 6 besser zeigen zu können.It should also be mentioned that for the sake of simplicity of illustration the tube 4 has not received any cross-sectional hatching, and so have the slits 6 to be able to show better.
